Carter noted that China is turning submerged reefs into airfields and military bases through land reclamation to bolster its sovereignty claims in the region, where territory is claimed by several different parties. At the same time, he also said that it is time for the US to demand China slow down its militarization of the Spratly islands while promoting new diplomacy to protects the rights and interests of all countries in the region.
Carter went on to say that the US Air Force was going to transfer "high-end assets" to the region as a means to counter Chinese expansion. It is a part of the Obama administration's "Asia pivot" strategy, he said. "After all, turning an underwater rock into an airfield simply does not afford the rights of sovereignty or permit restrictions on international air or maritime transit," he said.
Carter added that the United States will fly, sail,and operate wherever international law allows. While stating that Washington supports all claimants of the Spratly islands to settle their territorial disputes through peaceful negotiations, Carter also said that the US should and will do everything it can to defend freedom of navigation in the South China Sea.
